Error or misundertanding

[Jandisson]

Hi there,

I'm finishing my Phd on computer science and I will use GHTorrent in my thesis.

I'm having some problems to understand why there is some differences between the data coming from github and the data coming from ghtorrent.

Let's give an example:

1 - Clone https://github.com/vaadin/framework
2 - Take the first commit by doing git rev-list --max-parents=0 HEAD : d0b04c7fb28acc39ceeb63ea0c22f8568e7ca81d
3 - Search for this sha in the project_commit table
4 - It is not associated with the https://github.com/vaadin/framework project in ghtorrent. It is associated with 2 other projects that are copies of the vaandin project.

Could please help to understand why the commit d0b04c7fb28acc39ceeb63ea0c22f8568e7ca81d is not associated with the project in https://github.com/vaadin/framework inside the ghtorrent?

Thank you very much.
